Description

One lot of four 5963 tubes, similar to 12AU7, with lower plate voltage, suitable for pre-amps, or front section of amps, by RCA for Hewlett-Packard. Long grey plate, ring getter. Test Ratings: 4 x 95 on my Jackson 648s tester, minimum is 70, new tubes at about 100. SHIPPING: A big jump in shipping fees over the last two to three years due to the pandemic and the rising fuel cost. I am still trying to hold the shipping fee down to make it easy for the Buyers. Shipping to USA and Canada only with tracking. For Europe and Far East countries, please contact the Seller to get permission to buy ( due to higher tracking fees charged by Canada Post). Please pay in 3 days. Combined shipping is welcome. If you have paid for individual items and have surplus shipping fee paid for, I will refund you immediately when I send out the combined parcel.
